The NRTL Program, as well conformity assessment programs in general, have been the focus of several recent studies. The references below provide background information for program improvement initiatives and are provided as a point of reference.



Welcome to the Nationally Recognized Testing Laboratory (NRTL) Program Improvement project home page. The NRTL Program recognizes private sector organizations as NRTLs, and recognition signifies that the organization has met the necessary qualifications specified in the regulations for the Program. The NRTL determines that specific equipment and products meet consensus-based standards of safety to provide the assurance, required by OSHA, that these products are safe for use in the U.S. workplace.

This web page provides stakeholders with a single resource center on NRTL Program Improvement initiatives.
